Dual Whole House Filtration System

At Slim Thin Tanks we encourage customers to get the most out of rainwater harvesting, storage and usage. We use Onga pumps and Pentair filtration on all our installations.

For the best outcome, we recommend installing a pump and filtration system and plumbing your rainwater into your house. When plumbed into the toilets and laundry, the tank will continuously empty and refill. A dual filtration system is required if considering drinking your rainwater.
